All I see are spots

LOL!
There is a lot more than spots in the links.
For anyone with the tools and the talent, this is a great way to end up with a very, very good flashlight that can kick some arse with regular unleaded D cell alkaline batteries.

Whoops! I see a soldering gun, which lets me out since I always get cold solder joints (nearly blew up my stereo).

Perhaps someone will see a business opportunity here and start doing mods for the rest of us fumble-fingered Thumbelinas.

You can use a Cold Soldering Gun, which uses mystery stuff that I have forgotten. Anyway, basically, it creates an electrical current between the part and the solder, and melts the solder without creating broken solder joints, too much solder, cold soldering joints, etc.

Oh, and it can't burn you, because your resistive.

Nathan:
When I used my son's cold solder pen (gun), testing it out before component use, the insulation still bubbled, so I used heat sinks to absorb the heat build-up. I found heavy duty steel alligator clips work best. Of course, following what the Navy taught me, alcohol cleaning of the foil and leads followed by rosin remover leaves a very shinny connection. Dull looking, sure sine of a cold solder.
Enjoy the day,

That would be black bear.
